1958 model B&S engine with compressor, mounted on plate to go on a tank. Engine & compressor turn freely, may have been used on a milking machine, has been in a barn stored for several years. Would take very little to restore it, cleans up well, nice antique piece. Its a 6B-R6 engine. 902828 580521 are the engine numbers, 58 being the year code. I will take $75 for the complete setup. Has the original oil bath breather, some pics have it on, i took it off for some. Its all complete. Compressor says DECORA, Emoryville, California. $75
